The International Criminal Court (ICC, or “the Court”) has become a significant institution in international diplomacy. Its work alters leaders’ and states’ reputations, and affects diplomatic relations. Yet the ICC is not simply an institution created by and for states, nor is it a passive factor in the international community. The ICC seeks to be a legitimate criminal court, and to accomplish this it engages in network diplomacy: diplomacy conducted through building sustained connections between governments, corporations, non-governmental organizations (NGOs) and individuals, which can be used to achieve common goals.
